Engineered TiO 2 nanoparticles are also used in light-emitting diodes and solar cells. [6]: 82 In addition, the photocatalytic activity of TiO 2 can be used to decompose organic compounds in wastewater. [4] TiO 2 nanoparticle products are sometimes coated with silica or alumina, or doped with another metal for specific applications. [6]: 2 [10]
A nanoparticle or ultrafine particle is a particle of matter 1 to 100 nanometres (nm) in diameter. [1] [2] The term is sometimes used for larger particles, up to 500 nm, or fibers and tubes that are less than 100 nm in only two directions. [2]: 394 At the lowest range, metal particles smaller than 1 nm are usually called atom clusters instead.
Titanium dioxide, also known as titanium(IV) oxide or titania / t aɪ ˈ t eɪ n i ə /, is the inorganic compound derived from titanium with the chemical formula TiO 2.When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. [4]
Webster's research has examined the multiple uses of nanotechnology. His studies focus on the development, production, and assessment of nanophase materials as superior biomedical materials . [ 4 ] He has conducted in-depth research on the application of nanophase materials for tissue regeneration .
While advancement of research proves that targeting and distribution can be augmented by nanoparticles, the dangers of nanotoxicity become an important next step in further understanding of their medical uses. [25] The toxicity of nanoparticles varies, depending on size, shape, and material. These factors also affect the build-up and organ ...
Research is being carried out on the application of nanotechnology to glass, another important material in construction. Titanium dioxide (TiO 2) nanoparticles are used to coat glazing since it has sterilizing and anti-fouling properties. The particles catalyze powerful reactions that break down organic pollutants, volatile organic compounds ...
The method is used for the fabrication of metal oxides, especially the oxides of silicon (Si) and titanium (Ti). The process involves conversion of monomers in solution into a colloidal solution ( sol ) that acts as the precursor for an integrated network (or gel ) of either discrete particles or network polymers .
Nanotechnology's ability to observe and control the material world at a nanoscopic level can offer great potential for construction development. Nanotechnology can help improve the strength and durability of construction materials, including cement, steel, wood, and glass. [9] By applying nanotechnology, materials can gain a range of new ...
